(Created page with "== Introduction == Stress physiology is a branch of physiology that studies the effects of stress on the biological systems of organisms. This field encompasses the biochemical, cellular, and systemic responses to stressors, which can be physical, chemical, or psychological in nature. Stress physiology is crucial for understanding how organisms adapt to changing environments and how chronic stress can lead to various pathologies. == Historical Background == The study...") |

The neuroendocrine system plays a pivotal role in the stress response. The [[hypothalamus]] activates the [[sympathetic nervous system]] and the [[hypothalamic-pituitary-adrenal (HPA) axis]]. The HPA axis involves the release of [[corticotropin-releasing hormone (CRH)]] from the hypothalamus, which stimulates the pituitary gland to secrete [[adrenocorticotropic hormone (ACTH)]]. ACTH then prompts the adrenal cortex to release [[cortisol]], a key stress hormone. | The neuroendocrine system plays a pivotal role in the stress response.
